出现这个错误是因为zookeeper从某个版本之后就不会自动帮忙创建节点了。

这时候就需要改kafka配置文件(/kafka/config/server.properties)中的zookeeper.connect如下:

zookeeper.connect=127.0.0.1:2181

切记，端口后面不要加任何东西。

这个异常信息"Caused by: java.lang.IllegalArgumentException: Path must not be null" 是Java中常见的异常，它表示路径不能为空（null）。当你尝试使用一个空字符串或null值作为文件、目录或资源的路径时，就会抛出这个异常。这通常发生在文件操作、URL处理或者依赖于路径的操作中。例如，如果你试图创建一个新的File对象，但是传递的路径为空，就会引发此错误。
